I've followed Adrian's suggestion and uploaded a version of mozjs91
to experimental that uses the vendored copy of ICU, decoupling it from
this transition. jbicha is planning to upload that to unstable shortly.
This also has the advantage that more of the mozjs91 test-suite passes.
Several tests unfortunately make assertions about ICU behaviours that can
validly change from release to release, like the precise formatting of
datetime strings in various languages - I don't think Mozilla upstream
really support swapping it out for a system copy.

They would not, but it'll mean we can't be as confident about changes
made in Debian being equally valid for Ubuntu or vice versa.

That's interesting, 0ad built fine for me against 70.1 on a porterbox
(i386 on barriere) - and its vendored copy of mozjs78 is built with
i18n disabled (--without-intl-api), which should in principle disable
the ICU dependency. I'm not sure what's going on there.
mozjs78 is expected to FTBFS in most ICU transitions, because as with
mozjs91, its test-suite makes a lot of assertions about things that
are really ICU behaviours rather than mozjs behaviours, and change
from version to version. As Adrian suggested, I've done an upload to
experimental that switches it to use the vendored ICU. This can be
uploaded to unstable whenever needed.
After we move gjs from mozjs78 to mozjs91 (which jbicha is preparing now),
mozjs78 will only be in Debian for the benefit of cjs and
policykit-1/experimental, both of which I hope will move away from mozjs78
before bookworm.
